Agreed. For J to occupy both CPUs on a dual core machine, you'd need to be running two instances of J (and both would need to be cpu-bound processes). [Dan Bron and I were both using dual core machines when we did our timing tests on that matrix index code, but that's a circumstantial issue more than a relevant issue.] -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
